TL7709ACD TI Supervisory Circuit | 8-SOIC | 2.53V Threshold, Active Low Reset

Product Overview

The TL7709ACD from Texas Instruments is a monolithic integrated circuit designed as a supply voltage supervisor for microprocessors and digital systems. It provides a reset signal to the system when the supply voltage drops below a preset threshold, ensuring reliable operation during power-up, power-down, and brownout conditions. Housed in an 8-pin SOIC package, this device offers a precise voltage threshold of 2.53V (typical) with a hysteresis of 10 mV, making it suitable for 3.3V and 5V systems. The TL7709ACD features an active-low reset output with an open-collector configuration, capable of sinking up to 10 mA. It also includes a manual reset input (MR) for external triggering and a sense input (SENSE) for monitoring an external voltage. The device operates over a wide temperature range of -40°C to +85°C, ensuring robust performance in industrial and automotive environments.
